The program to control the entry of illegal drugs into the country

was a failure in 1987. If the program had been
successful, the wholesale price of most illegal drugs would not

have dropped substantially in 1987.
80. The argument in the passage depends on which of the following

assumptions?
(A) The supply of illegal drugs dropped substantially in 1987.
(B) The price paid for most illegal drugs by the average consumer

did not drop substantially in 1987.
(C) Domestic production of illegal drugs increased at a higher rate

than did the entry of such drugs into the
country.
(D) The wholesale price of a few illegal drugs increased

substantially in 1987.
(E) A drop in demand for most illegal drugs in 1987 was not the

sole cause of the drop in their wholesale
price.

答案选E 我总觉得怪怪的

那位nn把题目和各答案都分析下吧：）

My personal opinion:

when price drops, there are two possibilities: a drop in demand or an increase in supply(or both)

E says drop in demand is not the sole cause => other cause exist, that is supply increases (This is caused by failure in controling of illegal drugs)

有一个问题，如果按E的说法是不是应该改成not the cause of 而不是not the sole cause of.
